Organisations may include non-founder members with specific roles (treasurer, secretary, board members…) with higher permission levels, compared to the regular members. Members that have permission levels which include control over organisation finances represent a high risk for the organisation as there is a high risk of losing money if malicious members perform illegal transfers. That problem is especially present in the world of cryptocurrency where transfers cannot be revoked, once transaction is executed there is no rollback. The use of multisig might be an obvious solution, but the high overhead cost of writting multiple signatures on blockchain, even if the transaction is valid, may not be acceptable in many situations where there is a high frequency of transactions.
